RATCI-IET DRIVING MECHANISM FOR CUTTERS.

Application led November 19, 1913.

T0 all 'whom t may concern Be it known that 1, CHARLns P. BASS, acitizen of the United States of America, residing at Los Angeles, countyof Los Angeles, State of California, have invented a certain new anduseful Ratchet Driving Mechanism for Cutters; and l do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to ratchet driving mechanism for cutters, and itmay be said to consist in the provision of the novel and advantageousfeatures and in the novel and improved construction, arrangement, andcombination of parts and devices as will be apparent from thedescription and claim which follow hereinafter.

One object of the invention is to provide novel and improved drivingmechanism more particularly designed for use on apparatus for cuttingthe sinews of tough meat to make such meat very like tender meat so thatit shall be easy to cut and much more satisfactory to eat.

Further objects of the invention are to provide novel and improveddriving mechanism more particularly designed for use on apparatus of thenature specied which is simple and compact in construction, strong anddurable, economical to manufac` ture7 convenient to use, and effectivefor its purpose.

`Other objects and the advantages of the invention will be apparent tothose skilled in the art from a consideration of the following`description of the preferred form of vapparatus embodying it, taken inVconnection with the accompanying drawings in which- Figure 1 is a frontelevational view of the apparatus; F ig. 2 is a sectional view taken onthe line 2*2 of Fig. l; Fig. 3 is a broken sectional view taken on theline 3-3 of Fig. 1; Fig. 4 is a broken sectional view taken on the line4 4 of F ig. 1; and Fig. 5 view taken on the line 5 5 of Fig. l. y v

The frame of the apparatus consists of the base 6, preferably hollow onits underside, the uprights 7 disposed on opposite sides of the base 6,the vertical guides 8, the crosspiece 9 at the top of the uprights 7,the door l0 hingedly connected to the crosspiece 9, and ring handles l0on the uprights 7.

Specication of Letters Patent.

Patented J une 1, 19155. serial no. 802,004.

Gn the frame of the apparatus is movably mounted the sinew cutter 11which consists of a plurality of substantially vertical blades 12 havingthe top portions thereof secured to a cross-head 13 which latter has itsend portions disposed adjacent to the guides 8 and provided with rackteeth 11 thereon.

As shown, the top portions of the blades 12 are preferably arranged in aslit in the cross-head 13 and secured by screws 15 passing through thecross-head. lThe lower end of the blades 12 are sharp and preferablyformed with notches 1G to more effectively catch and cut sinews of meat.Each successive blade S is preferably disposed at right angles to thepreceding blade so that both longitudinal and cross sinews may be cut.Blocks 11 of suitable material are arranged adjacent to the guides 8 tocushion the sinew cutter.

The blades 12 pass through openings 17' in the cross-bar 18 whichprevents the meat being raised when the blades are raised. lThecross-bar 18 is preferably adjustable for different thicknesses of meatby means of brackets 19 on' the cross-bar which brackets are formed withslots 2O through which screws 21 pass into the frame of the apparatus.

A slide 22, provided with a handle 23 at the front thereof, has its endportions fitted in guideways 21 on the base 6 and is provided with rackbars 25 on its underside.

A shaft 26 bears in the uprights 7 and has thereon mutilated gears 27having teeth 28 adapted to mesh with the teeth 14e and raise the sinewcutter when the shaft is turned by the crank 29.

lt will be understood 29 is turned the sinew cutter is intermittentlyraised and allowed to drop so that the blades 12 penetrate and cut thesinews of meat placed on the slide 22. The blades 12 and the cross-bar18 areJ preferably nickel plated so as to clean easily. In cleaning theblades 12 the sinew cutter may be raised out of the frame of theapparatus through the door 10.

Automatic means is preferably provided for moving the slide 22 to havethe sinew cutter act on the whole piece of meat that may be placed onthe slide. The means shown consists of a shaft 30 which bears on thebase 6 and has thereon spur wheels 31 in mesh with the teeth of the rackbars 25;

that when the crank VA. dog 37 may be pivotally the shaft 30 beingoperatively connected with the shaft 26 by means of a cam 32 on theshaft 26 which cam bears against a bell crank 33 which latter ispivotally mounted on one of the uprights 7 and is pivotally connected toa pawl 3% which by means of a spring 35 is held against the ratchetwheel 36 mounted on the shaft 30. mounted on the base 6 and pressedagainst the ratchet wheel 36 by the spring 38. It will be understoodthat the automatic means just described effects an intermittent rearwardmovement of the slide 22 when the crank Z9 is operated.

The pawl 3% and dog 37 may be disengaged from the ratchet wheel 36 atwill to permit of the slide 22 being moved forward, by raising the head39 of the lever l() which latter is pivotally mounted on oneV of theuprights 7 and is provided with an arm 4l bearing against the par-.fl 34and has its rear end portion bearing on a bar 4t2 which latter bears onthe dog 37.

While one form of construction embodyl) ing the invention has beenparticularly illustrated and described, many changes and modificationsthereof will occur to those Y skilled in the art--wlierefore the rightis reserved to all suoli changes and modifica- Copies of this patent maybe obtained for ve vcents each, by laddressing the Washington, '1). 0;
